A lock of John Lennon's hair is being auctioned off.The late Beatle gave his shorn strands to hairdresser Betty Glasgow - who worked as a stylist on the Fab Four's films 'Hard Day's Night' and 'Help' -along with a note saying: "To Betty, Lots of love and hair from John Lennon. "The piece is being sold by English auction house Gorringes, in Worthing, as part of 'The Betty Glasgow Collection of Beatles and Film Memorabilia' on December 12, and is expected to reach between £2,000 and £3,000. For safe-keeping Betty stuck the hair inside a copy of John's second book,'A Spaniard in the Works'.She admits she will be sad to sell the hair because it reminds her of the fantastic times she had with John and the other Beatles - Sir Paul McCartney, the late George Harrison and Ringo Starr.Betty said: "It was great fun working with the boys on the films. They were always together in a group and having a laugh. My job was to keep their hair in order as the film was made over three months, so their trademark, mop-top hair cuts had to be regularly trimmed."But although all their hairstyles looked the same to the outsider, I knew all their secrets - George Harrison had a very dry scalp and, of course, Ringo had a grey streak which he hid by brushing it forward!"
